Creating Multiple Videos of a Dataset

This is an example of a run(scenario) script that creates multiple videos of the animation of results of the coarse-graining (cg) dataset of a scenario. The settings for the animation of the results is specified by a list of Particle Analytics Camera files (.pac) (see the following link on how export the .pac files: link)

''' This scripts loads the cg_dataset of a scenario and creates multiples videos of the results in the dataset
 based on the scene settings specified in a list of Particle Analytics Camera file (.pac). 
 Each video generates an MP4 file and is saved into the scenario'''
